Dictionary Management System

The Dictionary Management System (DMS) is a Web-based tool to develop and store a project command and telemetry dictionary. The dictionary defines a project’s flight/ground interface. In recent years, dictionaries have become very large, making it hard to maintain traditional methods of flat-file storage and manual...

Briefs : Software

Ensemble tools for different missions share a common look and feel, easing the transition of personnel between projects.

Success in mission operations relies on achieving consensus amongst a wide variety of personnel with diverse backgrounds and education. Previously, NASA missions relied on disparate tools with a variety of...

Development of Free Molecule Flow Equations from a Transient, Asymmetric Source

Molecular flow model is explored as a tool to describe an unusual variety of plume interaction issues.

The analysis and simulation of gases expanding from sources such as rocket nozzles into vacuum, or the effects plumes from these sources create when they...

Spherical Empirical Mode Decomposition

The spherical empirical mode decomposition algorithm is an adaptation in the spherical space of the 2D empirical mode decomposition in Euclidian space. This algorithm is a signal analysis method for any spherical data, such as orbital measurements. The two primary advantages of this innovation are the...

Bird Vision System

About 2.5 seconds after the launch of STS-114, the first Return to Flight launch after the Columbia accident, a large bird struck the external tank and fell into the exhaust plume. While this particular bird strike did not threaten the vehicle because it did not strike the orbiter, it did raise awareness of the threat of avian...

Selective Access and Editing in a Database

A complex organization with many tasks and sub-tasks, many phases, and many workers often will have an associated database with many users and groups, each of whom has a limited “need to know” (e.g. fine-grained security access controls) that does not extend to all information in the database. A...

Program Determines When MRO Observations Span More Than One Spacecraft Sequencing Period

Previously, the Mars Reconnaissance Orbiter (MRO) did not allow observations to go beyond the end of a planning period. However, opportunities for observing the Mars Science Laboratory (MSL) rover occur close enough to these boundaries to require the...
